Systematic Studies On Mymaridae In China (Hymenoptera: Chalcidoidea)

The present paper is based upon the examination of more than 2,000 slide-mounted specimens mainly collected by sweeping and yellow pan traps from all over the China. It consists of twenty-three valid genera and 108 species, in which, 46 species are new to science, 3 genera and 30 species are new records for China.The 23 genera from China are diagnosed, illustrated and keyed for both sexes. In each genus the following information is given: 1) generic synonomy; 2) important references; 3) geographic distribution; 4) diagnosis; 5) hosts; 6) notes on occurrence and general appearance; 7) included species known from China; and 8) specimens examined. When the genus is detailedly studied, a key to the including species is provided and full description of each species is proposed. The recorded species are briefly diagnosed. An illustrated overview of the external morphology of the family is presented to acquaint readers with basic structures and terminology.A cladistic analysis of the genera based on 64 characters is conducted to estimate the evolutionary relationships of the family. Because the relationships between Mymaridae and other chalcidoids are not clear, and the monophyletic mymarids possess some uniquely derived characters, the choice of mymarid outgroup is uncertain. Founded on Schauff' s (1984) comprehensive work, my analysis has chosen Gonatocerus and Ooctonus as outgroups of other genera.The list of the genera and the number of species under each genus treated in this paper is as follows. Those marked with an asterisk (*) are new records for China.1. Gonatocerus Nees, 43 spp., all identified and described2. Ooctonus Haliday, 11 spp., all identified and described3.
